Bayardella Johni
''Bayardella'' is a genus of small, neritiform cylindrical shelled gastropods belonging to the family Planorbidae. They are native and endemic to Australia. Species of ''Bayardella,'' like other Planorbidae, Planorbids, are non-operculate. Description The aperture (shell mouth) is typically almost as long as the entire shell with some specimens being described as 'almost abalone-shaped'. The species of ''Bayardella'', when adult, often display medium-sized shells that are usually 5-9mm in size. The shells often display heavy spiral ridges on the periostracum, have a deep Umbilicus (mollusc), umbilicus and have a margin to the Columella (gastropod), columellar that is reflected and curved slightly but without a fold. The shells of ''Bayardella'', like other Planorbidae, Planorbids, are typically Sinistral and dextral, sinistral. Ecology ''Bayardella'' can be found living on the underside of stones and pieces of wood (i.e. fallen logs or branches) in the upper reaches of small ...

Walcott Inlet
Walcott Inlet is an estuary located in the Kimberley region of Western Australia. It flows into Collier Bay, in the Indian Ocean, via a narrow gap known as Yule Entrance. The inlet was named on 19 June 1865 by Trevarton Charles Sholl after Stephen Walcott, Commissioner of the Government Emigration Board, while on an exploratory expedition from the short-lived Camden Harbor settlement (in Camden Sound). The inlet is in length, with a width of and covering an area of . It is tide-dominated, but in nearly pristine condition with a catchment area of . The entry to the inlet, known as Yule Entrance, On the Department of Agriculture, Water and the Environment websithere Date assumed per last date mentioned in publication (2010), and author as per website. is in length and as little as wide. The mean tidal range at the mouth is , but can reach , leading to turbulence, strong tidal flows and whirlpools. Three large rivers flow into the eastern end of the inlet: Charnley Rive ...

Isdell River
Isdell River is a river in the Kimberley region of Western Australia, named in 1898 by explorer Frank Hann after James Isdell, who was prominent in the region and later served as a member of parliament. The river rises in the Packhorse Range and flows in a south- westerly direction until it reaches Isdell Gorge at the foot of the Wunaamin Miliwundi Range where it changes to a north-westerly direction before discharging into the eastern end of Walcott Inlet. The river has eleven tributaries, including Sprigg River, Woolybutt Creek, Cadjuput Creek, Woomera Creek and Tulmulnga Creek.

Ephemerality
Ephemerality (from the Greek word , meaning 'lasting only one day') is the concept of things being transitory, existing only briefly. Academically, the term ephemeral constitutionally describes a diverse assortment of things and experiences, from digital media to types of streams. "There is no single definition of ephemerality". With respect to unique performances, for example, it has been noted that " hemerality is a quality caused by the ebb and flow of the crowd's concentration on the performance and a reflection of the nostalgic character of specific performances". Because different people may value the passage of time differently, ephemerality may be a relative, perceptual concept: "In brief, what is short-lived may not be the object itself, but the attention we afford it".Ronald Beiner, ''Political Philosophy: What It Is and Why It Matters'' (2014), p. 10. Ephemerality and nature Geographical features An ephemeral stream is that which only exists following precipitation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Victoria (Australia)
Victoria is a state in southeastern Australia. It is the second-smallest state with a land area of , the second most populated state (after New South Wales) with a population of over 6.5 million, and the most densely populated state in Australia (28 per km2). Victoria is bordered by New South Wales to the north and South Australia to the west, and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Great Australian Bight portion of the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid north-west. The majority of the Victorian population is concentrated in the central-south area surrounding Port Phillip Bay, and in particular within the metropolit ...

Planorbidae
Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs. Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. As a result, planorbids are able to breathe oxygen more efficiently than other molluscs. The presence of hemoglobin gives the body a reddish colour. This is especially apparent in albino animals. Being air breathers like other ''Panpulmonata'', planorbids do not have gills, but instead have a lung. The foot and head of planorbids are rather small, while their thread-like tentacles are relatively long. Many of the species in this family have coiled shells that are planispiral, in other words, the shells are more or less coiled flat, rather than having an elevated spire as is the case in most gastropod shells. Although they carry their shell in a way that makes it appear to be dextral, the shell of coiled pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
